A Series of Enthalpy/Entropy-Driven Reversible Dissolution/Reorganization Equilibriums in the System of Cu(NO3)2–HL–GdX3–H2O (HL=5-methylpyrazine-2-carboxylic acid; X=Cl, Br, NO3, ClO4) 
Sheng Zhang, Qi Yang, Xiangyu Liu, Gang Xie, Qing Wei, Sanping Chen and Shengli Gao

It is important for the directional design and preparation of molecule-based functional materials to explore the self-assembly behaviour of reaction components. In the present research, it is reported that a series of reversible dissolution/reorganization equilibriums between the initial reactant with the final products 15 occur in aqueous systems, which were determined to be enthalpy/entropy driven chemical equilibriums by single crystal X-ray diffraction and microcalorimetry.

Indigo Dreaming 
Ian D. Rae

Ian Rae, Roger Brown’s first Ph.D. student, explored dithiole chemistry but failed to synthesise thiolutin. Now a historian of chemistry, he recounts the story of J. F. G. Fletcher, who returned to Australia in 1919 after munitions work in Britain, dreaming of the synthesis of indigo from naphthalene. He succeeded, but was unable to commercialise the process.

Influence of Chemically Inert Cations on the Hydrogen-bond Network in the Bray-Liebhafsky Oscillatory Reaction 
Dragomir R. Stanisavljev, Ivana Ž. Ljubi? and Maja C. Milenkovi?

The effects of different alkali sulfates on the Bray-Liebhafsky (BL) reaction dynamics are investigated by comparing the changes in the oscillograms provoked by the same amount of added sulfates. Larger cations have more impact on the BL reaction mechanism. As cations are not directly involved in chemical reactions, they may influence the reaction mechanism by changing the structure of the surrounding water and hydrogen-bond dynamics. The obtained results support the idea that the extent of water hydrogen bonding plays important role in the BL mechanism.

Abdolali Alizadeh, Fahimeh Bayat and Long-Guan Zhu

The propellane skeletons occupy a privileged place in synthetic chemistry. Most of their synthetic processes are based on the introduction of a third ring on the framework of a fused bicyclic structure. However, only limited approaches to propellanes exist through multicomponent reactions. A sequential four-component approach to oxa-aza[3.3.3]propellanes has been developed.

A Magic Equation: Delta Bonds Plus Bicyclic Guanidinates Equals Strong Reducing Agents 
Carlos A. Murillo

An account is provided of how the destabilization of a delta bond in quadruple bonded species by bicyclic guanidinate ligands leads to record low ionization energies of thermally stable compounds and concomitant production of very strong reducing agents. This paper commemorates the 50th anniversary of the seminal paper published on September 18, 1964 in Science describing how interactions between d-orbitals lead to a quadruple bond in species with idealized D4h symmetry.

Improved Photocatalytic Activity of Copper Heterostructure Composites (Cu–Cu2O–CuO/AC) Prepared by Simple Carbothermal Reduction 
Hongchao Ma, Yifeng Liu, Yinghuan Fu, Chunling Yu, Xiaoli Dong, Xiufang Zhang, Xinxin Zhang and Wenping Xue

Activated carbon-supported Cu–Cu2O–CuO heterostructure composites with effective visible-light activity have been successfully synthesized by simple carbothermal reduction. The Cu–Cu2O–CuO/AC heterostructure composites showed excellent photocatalytic activity compared with other catalysts (pure CuO, Cu2O/AC, CuO/AC, and Cu2O–CuO/AC), which is ascribed to synergistic action between the AC support and photoactive copper species, and efficient transfer and separation of photogenerated carriers at the hetero-interface (e.g. Cu2O/CuO, Cu/Cu2O or Cu/CuO and Cu2O/Cu/CuO). Moreover, the composition of Cu–Cu2O–CuO /AC can be tailored by varying the Cu loading, heat-treatment temperature, and heat-treatment time.

Diradical Character of Benzo- and Naphtho-Annelated Thiophene–Pyrrole Mixed Oligomer Dications 
Takuya Kageyama, Shunsuke Uneme, Masayoshi Takase, Kotohiro Nomura and Tohru Nishinaga

Cationic oligothiophenes are extensively studied as models of p-doped polythiophenes. However, little is known about the relationship between the structure and diradical character of the dications. In this study, a benzo-annelation process afforded enhancement of the diradical character, thus showing potential for designing π-conjugated oligomers for supramolecular chemistry based on π-dimerisation of radicals.

blank image
Robert G. Gilbert and Mitchell A. Sullivan
pp. 538-543

Glycogen is a complex branched glucose polymer which functions as a blood-sugar buffer in humans. The distribution of molecular sizes of this molecule is found to be quite different in diabetic and healthy mice. Exploring the polymer science underlying this observation gives hints as to possible new drug targets for diabetes.

pp. 592-597

Star polymers were synthesised using poly(amido amine) dendrimers as multifunctional initiators for the ring-opening polymerisation of ε-Z-l-lysine N-carboxyanhydride, followed by acid de-protection to yield water-soluble cationic poly(l-lysine) stars. Post-functionalisation of the star polymers with poly(ethylene glycol) was performed. Quantitative complexation of the star polymers with oligodeoxynucleotides was achieved at a nitrogen-to-phosphate ratio of 5.

pp. 598-602

Polypeptide nanocoatings were fabricated via surface-initiated ring-opening polymerization of amino acid N-carboxyanhydrides (NCA) to tailor the surface-wetting properties of a range of organic and inorganic substrates. The nanocoating thickness, surface roughness, and wettability were tuned by controlling the polymerization time and the type of NCA derivative used (i.e. lysine or valine). Whereas poly(l-lysine) coatings are hydrophilic, poly(l-valine) coatings exhibit water-repellent properties.

pp. 636-643

Synthesis of hyperbranched dendrimers up to third generation with N-phenylcarbazole as surface group and anthraquinone as the core unit has been achieved. The fluorescence decay studies of the dendrimers indicate that the highly branched third-generation dendrimer has a longer relaxation time than the zero-, first-, and second-generation dendrimers. Similarly, higher-generation dendrimers show better antioxidant behaviour with 1,1-diphenyl-2-picryl hydrazyl (DPPH) than the lower-generation dendrimers.
